A Los Angeles County sheriff's deputy was charged Thursday with assaulting inmates at the Twin Towers Correctional Facility and the Compton Courthouse lockup and falsifying police reports.

Deputy Jermaine Jackson was arrested after several months of investigation revealed that the 35-year-old Corona resident had allegedly assaulted two inmates on two separate occasions using his feet, which are considered a deadly weapon, said Steve Whitmore, a spokesman for the Sheriff's Department.

Jackson is charged with four felony counts of assault under the color of authority and two misdemeanor counts of falsifying police reports, according to Sandi Gibbons, a spokeswoman for the District Attorney's Office.

The complaint said one assault occurred Dec. 31, 2009, at the Compton Courthouse lockup and the other on Dec. 25, 2010, at the Twin Towers Correctional Facility, Gibbons said.

Jackson was arrested about 4:30 p.m. Thursday by deputies from the sheriff's Internal Criminal Investigation Bureau, Whitmore said. He was relieved of duty without pay, Whitmore said.

Jackson, who had worked at the Twin Towers Correctional Facility for five years, was booked into Los Angeles County jail system. Bail was set at $100,000.
